Abstract

The invention discloses a brake device for a rail line trolley, and belongs to brake devices of construction rail vehicles. The device comprises a frame, a wheel pair is arranged at the bottom of the frame; a transmission mechanism and a brake mechanism are mounted on the frame; the transmission mechanism comprises a supporting seat mounted at the end part of the frame; one side of the transmission rod is hinged to the supporting seat; the push rod is mounted at the top of the transmission rod; the brake mechanism comprises a brake pad which is arranged opposite to a roller on the wheel pair; one end of the brake pad support is connected to the brake pad, and the other end of the brake pad support is connected with the transmission rod; a spring connecting sheet II and a spring connecting sheet I are respectively arranged at the bottom of the frame and on the side wall of the transmission rod; a spring is arranged between the second spring connecting part and the first spring connecting part. According to the invention, the problems of low braking efficiency, high operation risk, high sliding probability and incapability of standardized operation of a trolley used in conventional rail transit line construction are effectively solved.

Description

technical field [0001] The invention relates to the technical field of brake devices for construction rail vehicles, in particular to a brake device used for small flat cars on rail lines. Background technique [0002] The small flat car used in the construction work surface of the urban rail transit track line mainly realizes deceleration and braking through human pulling or pushing during the driving process. The braking efficiency is low, the operation risk is high, and the probability of slipping the car is high, so it has a certain degree of safety. Risky and difficult to achieve standardized operations. Contents of the invention [0003] The technical problem to be solved by the present invention is: to provide a brake device used by small flat cars on rail lines to solve the problem of low efficiency, high operational risk, and high probability of slipping of cars used in conventional rail transit line construction. , the problem of not being able to standardize ho...
